Hi,
I have an application that uses DWR. It works fine in previous Liferay versions (Liferay 5.1).
Curiously, it works fine in Liferay 5.2.3 with Tomcat 5.5.
But, when I use the Liferay 5.2.3 with Tomcat 6, the next exception is thrown when it tries to obtain the DWR javascript proxy of my object:

The war I deploy is exactly the same for Liferay 5.2.3 with Tomcat 5.5 and for Liferay 5.2.3 for Tomcat 6.
Also, the code works well in a standalone Tomcat 6.
I'm using the latest stable DWR version: DWR 2.0.5
Any idea?
